Step-by-step explanation:
The formula for the area of a circle is pi x radius squared. So since we know the diameter we can take that and half it giving us radius. Than we plug radius in the formula, so 6.5 squared is 42.25. You than multiply it by pi, and not 3.14 because theirs a possibility of being a couple units off when rounding, and after multiplying it you'll be left with the answer of 132.73
Answer: 132.73
Answer:
5, 6, 39
Step-by-step explanation:
Answer:
=615.44 m^2
Step-by-step explanation:
The area of the circle is given by
A = pi r^2
= pi (14)^2
= (3.14) 14^2
=615.44 m^2
The gcf of 18 and 20 is 2, so your answer is:
2(9+10)
Answer:
25 pages
Step-by-step explanation:
Create a proportion:
=
= 
Cross multiply and solve for x, the number of pages in 75 minutes:
60x = 1500
x = 25
So, he can read 25 pages in 75 minutes at the same rate
